The Bryozoa of the Tortugas Islands, Florida. 219 



Charlotte Islands, has not hitherto been noted on the American side of the 

 Atlantic. It is abundant at the Tortugas from low water down to several 

 fathoms, growing profusely over piles, shells, seaweed, and sponges. The 

 zooecial wall in all cases was thickly covered with a layer of coral mud. 

 Occasional individuals showed the swelling at the side of the zooeciostome 

 which forms the ooecium. Embryos in various stages of development were 

 present. 



Genus Anguinella van Beneden, 1844. 



Anguinella palmata van Beneden. 



Van Beneden, 1844, p. 58.— Busk, 1856, p. 95. — Osburn, 1912, p. 253, pi. xxviii, 

 fig. 78. 



This species occurs rather sparingly among algae on the reefs in shallow 

 water. It is very easily overlooked because its irregularly branched form 

 gives it a marked resemblance to some of the smaller algae. The species is 

 now known to occur on the American coast from the Tortugas to Buzzard's 

 Bay, Massachusetts (Osburn, 1912). At Beaufort, North Carolina, it is 

 very abundant and grows much larger than at the localities mentioned 

 above. It has not previously been noticed south of Charleston, South 

 Carolina, where it was recorded by Busk (Harvey, coll.). 



Genus Amathia Lamouroux, 18 12. 

 FAmathia goodei Verrill. 



Verrh^l, 1901, p. 329. — (?) Smitt, 1872, p. 4 {Serialaria sp. undet.). 



Several colonies, growing attached to piles, seem to belong to this 

 species, which Verrill described from the Bermudas. Verrill described the 

 branches as "thick, soft and flaccid" and the zooids as "numerous, arranged 

 in large, dense elongated clusters composed of several close rows, which 

 often nearly or quite surround the stem, but are scarcely at all spiral."
